... The magnitude of the force F on the cart increases in direct proportion to the distance x that the cart is displaced from the equilibrium point (x=0). If you double x , then you double F. The constant k is the proportionality constant between F and x. The minus sign in F = kx indicates that the for ...

Momentum and Impulse
... The Conservation of Momentum Momentum is a useful concept. In any mechanical system composed of mutually interacting objects, though not subject to external forces, the net linear momentum remains unchanged. This is the law of the conservation of momentum. The law has two mathematical forms describi ...

Newton`s Second Law
... Isaac Newton formulated three fundamental laws of motion: 1. Every object continues in its state of rest or of uniform speed in a straight line unless it is compelled to change that state by a net force acting on it. 2. The acceleration of an object is directly proportional to the net force acting ...
